Brief Answer:
Start with diet changes and exercises...
Detailed Answer:
Yes, the
LDL number is high enough to put you at significant risks. I would start with modifying your diet and adding more exercise to your life style. It might help to plan a personalised
diet plan from a nutritionist and stick to it. In general I would add plenty of fibre rich whole grain cereals, green leaves and fruits, nuts/dry fruits, fish, egg, ginger, garglic, onions and chilli pepper (capscium) to the diet. You also need to start daily
aerobic exercise, brisk walking, cycling, swimming,
yoga and pranayama. In addition, you can take help of medicines -
statin and fibrates. Your physician will know about this medicine.
Hope this helps. Let me know if you need clarifications.
